i added Renthal twin wall bars. RC 922, they are 1 1/8inch so new risers as well, i am OK with this because if you take out your risers you will find they are machined out of one piece of material, if they snap in a fall you are screwed if there isn't a dealership around
at least this way round i can go and get a new bolt and ride off, problem resolved
the risers are Outlaw heavy duty, all the wiring and cables fit just fine
